The first thing that gives you an idea of what's going on is the plot of the wavelength correction from the combined iodine exposures for each order.

You can see that there is a characteristic shape for each order, and an overall slope across the orders.

How does each individual run compare? So, the naming convention used here is: the first number is the date of the run (it's either Oct 3rd, 4th or 5th). The second number is the number of the run (0, 1, 2, 3).

(One quick note — the wavelength along the bottom is from order 58. Each of the other orders are overplotted on the same x-axis to give a comparison).

I plotted all of these plots with the same x and y ranges so you can see the relative shifts. You can definitely see that there is less of a spread within a run, than between runs.

A quick movie that shows this…

I also combined things for each order to see if there is some kind of order - dependent effect.
